The central principles of dynamics have been summarized in a series of statements known as Newton’s laws of motion

Isaac Newton

Sir Isaac Newton was an English physicist and mathematician who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. He graduated from University of Cambridge.His book Philosophiæ Naturalis Principle Mathematica first published in 1687, laid the foundations for classical mechanics. Newton made seminal contributions to optics, and he shares credit with Gottfried Leibniz for the development of calculus.

(1642~1726)

Newton recognized that the force that causes an apple to fall to the ground was the same force that caused the moon to fall toward the earth.

Newton’s work grew from his study of gravitational attraction between astronomi- cal bodies using differential calculus. Eventually, he published his findings, which included his three laws of motion that defined the concepts of force mass, and momentum, in his famous work Principia.

Newton’s laws of motion

Newton’s laws of motion

1st Law

system at rest will remain at rest, and a moving system will move continuously with a constant velocity unless acted on by outside unbalanced forces.

2nd Law

2nd Law

The acceleration of a system is directly proportional to the sum of the forces (resultant force) acting on the system and is in the same direction as the resultant.

1st Law

3nd Law

Newton’s third law reveals that every force is always accompanied by a second force acting in the opposite direction. It has been said, “You cannot touch without being touched.”
